I, as an owner of a Bella Lightspeed with 650c wheels, had little choice for my selection. At 4'10" when I looked for a new road bike, I wanted a bike that fit. I was tired of 'make do' with what was out there. Now, at 4'9.75" or less, I am happy with the 650c's on my bike. I sure wish I could ride a bike with 700c wheels, but I can't!! or do I say, I shouldn't ... I am happy with Bella, because it will be the last road bike I purchase, I hope/... My mom, bless her heart, had shrunk in inches to 4'6" before she died. My twin still holds out to be 4'11". I know, as I get older, I won't be as tall and at close enough to be 56, I want a bike that will last me until I can no longer ride and that probably means when I am dead because I hope to be riding in some fashion until then!!! I am in the market for a new commuter and it has become increasingly difficult to find something that will fit me until I am 65 and hope to retire...I may just save enough pennies for that custom bike
